Definitions

  • the invention relates in particular to an assembly for a lighting and / or signaling device of a motor vehicle.
  • actuator is meant an electrotechnical element, engine type, associated with a kinematic chain allowing the movement of a target element.
  • an actuator comprises an electronic control card for managing its operation.
  • the actuator block present in the projector device is multifunctional: it allows a first function consisting in the tilting of a pivoting flap within the projector device, and a second function, called DBL function.
  • dual-function projector which combines the functions of dipped beam and long range lights: for this purpose, it can for example be placed inside the projector bifunctional rotating cover that can be placed on command of a first position in which it obscures part of the light signal produced by the light source of the projector, the range of the projector is thus limited to that of the dipped beam to not dazzle other drivers at a second position in which it does not obscure the light signal produced by the light source of the headlamp, the range of the headlamp then corresponding to that of the high beam, as described in the patent EP 1 197 387 .
  • This exemplary embodiment is mainly implemented in elliptical projectors devices.
  • a mobile cover can adopt more than two positions to obscure in a few ways, selectively, the light beam emitted by the source: it can thus have caches bi function traffic code right / traffic code left, caches tri-function traffic code right / traffic code left / route etc ...
  • the present invention particularly relates to multifunctional devices.
  • this motor must be integrated in a very hot area, because of the proximity to the light source, while occupying the smallest space for reasons of space.
  • the invention aims in particular to meet the multiple requirements above.
  • the motor is permanently mounted in the support housing without the aid of screws or additional parts, which simplifies the assembly operations and also reduces the space requirement by the absence of additional parts ( eg vis).
  • the motor is mounted in the support housing irreversibly, ie movement of the motor in the direction of disengagement thereof from the housing would damage the housing and / or the motor.
  • the motor comprises a plate, in particular metal, for example steel, stainless steel or aluminum, arranged to participate in fixing the motor in the housing.
  • the motor comprises a rotary shaft of longitudinal axis, and the plate extends substantially perpendicularly to this longitudinal axis of the engine.
  • the plate is disposed on one side of the motor, on the side of the rotary shaft.
  • the motor comprises at least one claw arranged to be able to bite into the material of the housing of the support.
  • the invention thus makes it possible not to be dependent on the creep of the material, in particular of the plastic material of the support.
  • the motor is somehow mounted rigidly in the housing.
  • the claw is made on the engine plate, in particular on a slice of this plate.
  • the plate may comprise at least two claws arranged on two opposite sides of this plate, on the edge thereof.
  • the plate may comprise, on the same side of its edge, at least two adjacent claws.
  • the motor and in particular the plate, comprises at least two claws, one protruding in a first direction and the other claw in another direction, including a direction perpendicular to the first.
  • the motor comprises at least one detent element arranged to cooperate with a complementary latching element on the support.
  • said detent element on the motor corresponds to an orifice formed on the plate
  • the support comprises at least one detent tab arranged to snap into said hole of the plate.
  • the plate is arranged to be mounted in two lateral slots of the support housing.
  • the plate comprises at least one wedging element arranged to allow the wedging of the plate in the housing, in particular in said slots.
  • the wedging element may comprise a boss formed on a face of the plate.
  • the plate participates in mounting an electrical connector on the motor.
  • the motor may comprise a collar of which the rotary shaft of the motor protrudes, and this collar is arranged to engage in a passage of the support, in particular to guide the motor relative to the support during assembly.
  • the motor comprises a rotary shaft integral with a pinion arranged to cooperate with a gear wheel for actuating covers.
  • the invention also relates to a motor, particularly for an assembly as defined above, comprising a plate arranged to participate in fixing the motor in the housing.
  • the invention also relates to a lighting and / or signaling device of a motor vehicle, including a motor vehicle headlamp, comprising an assembly as defined above.
  • the device may comprise a plurality of covers to form light beams of different types, for example a code beam, a motorway beam and a road beam, these caches being actuatable by the stepper motor or a motor of another type.
  • the assembly with the motor is disposed substantially between a reflector and a lens of the device.
  • This type of stepper motor is capable of generating and reproducing, under the environmental conditions of the automobile projectors, micro-displacements compatible with positioning accuracies of the required beam cuts, in particular such as to avoid glare from other users. .
  • stepper motors which are most often of the "bipolar" type, namely equipped with two windings driven quadratically in current, require a control electronics.
  • the motor 5 is permanently mounted in the housing 3 of the support 2, without the aid of screws or additional parts.
  • the motor 5 is inserted into this housing 3 in an insertion direction F, towards the perforated bottom 9.
  • the motor 5 is mounted in the housing 3 of the support 2 irreversibly, namely a movement of the motor 5 in the direction of disengagement thereof from the housing 3 would damage the housing and / or the engine 5.
  • the motor 5 comprises a plate 6, in particular made of metal, arranged to participate in fixing the motor 5 in the housing 3.
  • the motor 5 comprises a rotary shaft 7 of longitudinal axis X, and the plate 6 extends substantially perpendicularly to this longitudinal axis X of the engine.
  • the plate 6 is disposed on a face 8 of the motor, on the side of the rotary shaft 7.
  • the motor 5 comprises a plurality of claws 10a-10e arranged to be able to bite into the material of the housing 3 of the support 2.
  • the claws 10a-10e are formed on the plate 6 of the motor 5.
  • Some claws 10a, 10b and 10e are on a slice 12 of this plate 6.
  • the plate 6 comprises claws 10a and 10b on the one hand, and 10e on the other hand, arranged on two opposite sides of this plate 6, on the edge 12 thereof.
  • the claws 10a and 10b are arranged close to each other, being for example adjacent.
  • the claws 10a, 10b and 10e protrude in a first direction Y and the claws 10c and 10d project in another direction, namely the direction X perpendicular to the first direction Y.
  • the claws are, in the example described, made in one piece with the plate 6.
  • the plate 6 comprises a detent element 20 arranged to cooperate with a complementary latching element 21 on the support.
  • said latching element on the plate corresponds to an orifice 20 formed on the plate 6, and the support comprises a latching lug 21 arranged to snap into said hole 20 of the plate.
  • the plate 6 is arranged to be mounted in two lateral slots 25 of the housing 3 of the support 2, as visible on the figure 3 especially.
  • the plate 6 further comprises two wedging elements 27 (projecting in the X direction), on two sides of the plate 6, close to the bottom 9, arranged to allow the locking, along the X axis, of the plate 6 in the slots 25.
  • the wedging element may comprise a boss 27 formed on a face of the plate 6.
  • the plate 6 participates in the mounting of an electrical connector 30 on the engine 5.
  • This connector 30 allows in particular the power supply of the engine 5.
  • the motor 5 comprises a flange 31 of which the rotary shaft 7 of the motor protrudes, and this flange 31 is arranged to engage in a passage 32 of the support, to guide the motor 5 relative to the support during assembly.
  • the rotary shaft 7 is integral with a pinion 33 arranged to cooperate with a toothed wheel, not shown, for the actuation of covers.
